Content caching

Good, it finds a content cache. Is it the one you expect?

It does not find any configured public IP address ranges. That is normal if you have only one public IP address. Do you use more than one?

Is your public IP address "associated with your iTunes Store region," as specified in Content types that macOS Server caching and macOS caching support, or do any of the other exclusions listed there apply to you?

Yes, No, and No.

Well, there is more to updates it seems that what Apple advertises.

It appears that after the update, Content Caching seems to be working.

I updated this morning but did not test until a moment ago. Thanks

for the log tips. Someone needs to wrap a GUI around this stuff

like Apple eliminated from Server. Mmmm.....

Anyway, I digress. went through my purchases to fin something I had

previously deleted from my Macs (replaced by a better non-app store version).

On the server, started log streaming per the command you gave (thanks again).

On Mac 1, downloaded the app from the Mac App Store. The log started

spewing a stream of stuff and sorting through it received a request cached it

and served it. On status it correctly showed additional cache used and that it stored

and served.

Then the acid test on Mac 2. Proceeded to do the same. Again log spewed, indicating

a request was received and based on the log was served from cache!!! The status function

also backed it up, not showing any additional stored from origin but showed the additional

returned to clients.

So it does seem that Apple slipped more into the Supplemental Update than stated

(pretty much had to with 1GB download size). This did not work at all previously.

So, so far so good, Will monitor closely (and maybe think about how much work it

would be to wrap something more user friendly around all this, like it used to be).

What do you think I could have done wrong?

From what you describe, absolutely nothing.

For what it's worth I haven't observed any obvious results either, and I am wondering if it even works yet. Did you investigate the Advanced Options in Sharing?

What is the AssetCache process doing in Activity Monitor? Anything?

Content Caching is a joke and simply does not work!

I have 4 Macs, all associated with the same Apple ID on the

same network, all app and Apple update requests made from

the Mac App Store with the same Apple ID are completely and

totally ignored! No change in the amount of cache size, all Macs

continue to download directly from the app store.

Another useless or broken feature!

What do you mean by "holes in the process"? For most folks the instructions are: turn it on, and restart any devices you expect to use it immediately. (If you don't restart them, they will eventually discover the new content cache but not right away.) The AssetCacheLocatorUtil command can help troubleshoot content caching issues. You only need advanced settings if your network is complex or uses multiple public IP addresses.

The parents feature is for complex networks with multiple content caches. A child content cache downloads from its parent content cache(s) instead of directly from Apple. If you have only one content cache, or more than one but they're on the same subnet, you should not specify any parents.

Posting that long list of results would have been helpful. Did it report the content cache(s) you expect?

FWIW, I had run the command line:

AssetCacheManagerUtil status

on the Mac I chose as "the server" and it show zero, zilch, nada,

nothing in terms of any activity whatsoever even though on multiple

Macs I downloaded apps as well as Apple updates?

The only thing that wasn't zero was cache allocated, oh, and the date.

It is totally useless!

Does your disk have at least a few GB of free space? Content caching doesn't do much on a nearly-full disk.

Also, what does AssetCacheLocatorUtil report? Complaining might feel good, but we can't help you without data.

....

I would thing setting a cache size of 150 GB on a 500GB disk that has nothing

else on it would suffice.

All it has is zeroes, zeroes, and more zeroes as previously stated.

It was all good until it was decided to yank it from the Server app.

Can't even easily get logs now, just a summary. When it was part of the

server app, you just opened the service log to see what happened or didn't.

As it is now, there isn't (at least easy ) way to have a clue as to trace what may

be happening (or not).

As its man page states, "AssetCache logs to the os_log(3) subsystem com.apple.AssetCache." Read the man pages for os_log and the log command. You can use log show --predicate 'subsystem == "com.apple.AssetCache"' to show past log messages and log stream --predicate 'subsystem == "com.apple.AssetCache"' to monitor new ones.

You seem to be running AssetCacheManagerUtil status, not AssetCacheLocatorUtil. Run AssetCacheLocatorUtil on a Mac that is not using your content cache (not on the Mac where content caching is running), and examine the results. Posting the results here will let us help you.

here it is FWIW and BTW, haven't checked function after the supplemental update,

though it was not specifically addressed but at almost 1GB....:

"those values again returned to zero"

This is just a side effect of the content cache relaunching, because those values are only since the last launch. Content caching relaunches every time the computer wakes up, for instance.
